Whether you drink beetroot juice or not, your skin temperature goes down about the same amount when you're in a cool room.
Scientific Claim
Cool air exposure (20°C) does not significantly alter mean skin temperature in healthy young males between nitrate-supplemented and placebo conditions, with mean skin temperatures of 28.3 ± 0.5°C in nitrate-supplemented conditions versus 28.2 ± 0.4°C in placebo conditions.
Original Statement
“Mean skin temperature was stable over time in PL-Norm (P > 0.05) but declined relative to baseline at 1 (P = 0.04), 2 (P = 0.03), and 3 h (P < 0.05) in BR-Norm. In PL-Cool and BR-Cool, thermal sensation, mean skin temperature and forearm skin temperature were lower at 1, 2, and 3 h versus baseline (all P < 0.01, Table 1), but no differences were observed between PL-Norm and BR-Norm or between PL-Cool and BR-Cool at any time point (all P > 0.05; Table 1).”

Can make definitive causal claims
Assessment Explanation
The study design allows for causal inference about this specific comparison. The language accurately reflects the lack of significant difference without overgeneralization.
